In a TMR exclusive, the next generation VF Commodore has been spied undergoing road trials in country Victoria ahead of its debut in 2013.

According to a reliable source, one car (the first in the video sequence) is an entry-grade Omega, while the second appears to be a performance variant along the lines of the SV6 or SS.

There's lots of camo obscuring the sheetmetal, but there are still plenty of clues about the VF Commodore's final form.

The most obvious giveaway is the door apertures, which are unchanged over the current Commodore. That suggests the VE's core structure will essentially carry over to the new car, and critical dimensions like wheelbase will remain unchanged.

Cabin styling will come in for a substantial revamp though, and although precise details of these changes are scant we can see what appears to be a new chrome-ring treatment around the instrument panel in these test cars.

Outside, the VF will wear all-new body panels at both front and rear. Holden has secured Federal Government funding to help develop new lightweight material technologies. Rumour has it that these technologies will result in featherweight aluminium body panels for the VF Commodore.

What these panels will look like is hard to discern, but it's clear from this video that the performance model will wear a prominent ducktail spoiler on its bootlid and have an aggressively-styled and heavily vented front bumper.

The shape of the bootlid itself also appears to have come in for a significant change, with the bootlid's top surface now much higher than where the top of the tail-lights would be - a stark contrast to the slabby rear end of the VE Commodore.

This video also constitutes our first look at the upcoming Chevrolet SS, the export version of the VF Commodore that's destined for the US market in late 2013 or early 2014.
